RELiON RB52 offers abundant power in a small footprint. It is versatile and compact enough to be used in many marine applications including smaller boats with lower battery requirements, boats that require two of the same batteries and boats with electrical systems designed for just one battery.\r\n\r\nThe RB52 is a lithium iron phosphate (LiFePO4) battery with more power, less weight and up to 10x longer life than its lead-acid counterparts. Lithium is the logical choice for marine applications where you need a longer run time and reliability. RELiON lithium batteries provide more energy for high consumption than traditional lead-acid batteries. Lead-acid batteries also need to be maintained. If they are not maintained properly, their life span is shortened. Because lithium batteries require no active maintenance, a one-time purchase guarantees better lifetime value.\r\n\r\nApplications: Marine, Recreational Vehicles, Solar, Camping, AWP \u0026amp; Floor Machines\r\n\r\nElectrical Specifications\r\nCapacity @ 25A: 120 min\r\nResistance: ≤50 mΩ @ 50% SOC\r\nEfficiency: 99%\r\nSelf Discharge: \u0026lt;3% per Month\r\nMaximum Modules in Series: 4\r\n\r\nMechanical Specifications\r\nCell Type: Cylindrical\r\nChemistry: LiFePO4\r\n\r\nDischarge Specifications\r\nMaximum Continuous Discharge Current: 50 A\r\nPeak Discharge Current: 100 A (7.5 s ±2.5 s)\r\nBMS Discharge Current Cut-Off: 170 A ±20 A (10 ±5 ms)\r\nRecommended Low Voltage Disconnect: 11 V\r\nBMS Discharge Voltage Cut-Off: 8 V (2.0 ±0.08 vpc) (140 ±60 ms)\r\nReconnect Voltage: 9.2 V (2.3 ±0.1 vpc)\r\nShort Circuit Protection: 200-600 µs\r\n\r\nCharge Specifications\r\nRecommended Charge Current: 2.5 A - 25 A\r\nMaximum Charge Current: 52 A\r\nCharge Current 32° to 14°F (0 to -10 °C): ≤0.1 C\r\nCharge Current -4° to 14°F (-20 to -10 °C): ≤0.05 C\r\nRecommended Charge Voltage: 14.2 V - 14.6 V\r\nBMS Charge Voltage Cut-Off: 15.6 V (3.9 ±0.025 vpc) (1.1 ±0.4 s)\r\nReconnect Voltage: 15.2 V (3.8 ±0.05 vpc)\r\nBalancing Voltage: 14.4 V (3.6 ±0.025 vpc)\r\n\r\nTemperature Specifications\r\nDischarge Temperature: -4 to 140 °F (-20 to 60 °C)\r\nCharge Temperature: -4 to 113 °F (-20 to 45 °C) *Refer to charge currents below 0°C (32°F)\r\nStorage Temperature: 23 to 95 °F (-5 to 35 °C)\r\nBMS High Temperature Cut-Off: 176 °F (80 °C)\r\nReconnect Temperature: 122 °F (50 °C)","brand":"RELiON","offers":[{"title":"Default Title","offer_id":51865070665992,"sku":"REL-RB52","price":562.68,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/5825\/9208\/files\/e18b4c75-fc4d-489a-80d5-fcde70ef0a6c.jpg?v=1751364019","url":"https:\/\/mecleisure.co.uk\/products\/relion-128v-52ah-4sc-lifepo4-lithium-ion-battery-rel-rb52","provider":"MEC","version":"1.0","type":"link"}
